された緊定かもはや保証されなくなる。The tensioning rails currently used in sheet-fed printing presses are generally mounted in sliding guides in the cylinder groove. The tensioning rail is moved in the circumferential direction of the form cylinder using adjustment means, for example an adjustment screw, and the printing form is automatically tensioned on the circumference of the form cylinder. It is also possible to extend or axially move the rear plate edge to compensate for register errors. However, the sliding guide must be constructed with narrow tolerances in order to ensure play-free adjustment of the tensioning rail. Furthermore, a spring is required to return the tensioning rail to its starting position and to ensure play-free adjustment via the adjustment means. In conjunction with dampening solutions and plate cylinder treatments such as cleaning agents in offset printing presses, the sliding guides become easily soiled and corroded, with the result that the precisely registered tension of the printing plate is affected. It is no longer guaranteed.

正確な緊定を保証するようにすることである。An object of the present invention is to improve the support mechanism of the tensioning rail of the drum groove in consideration of the drawbacks of the above-mentioned known techniques, so that the support mechanism is less susceptible to the influence of the plate cylinder treatment agent and dampening water, and the height of the plate plate is high. The purpose is to ensure accurate tightening with precision.

るようになっている。In order to achieve this object, the invention provides that the tensioning rail for the front end of the printing plate is supported on a spring element, which spring element is designed as a leaf spring.
While the leaf spring allows elastic movement of the tensioning rail in the circumferential direction of the plate cylinder, it prevents movement transverse to this direction of elastic movement, and the rear plate edge The tensioning rail for the plate cylinder is supported on a spring element, which is designed as a round bar spring, which enables an elastic movement of the tensioning rail in the circumferential and axial direction of the plate cylinder. It is supposed to be done.

せ調節固定される。With this embodiment of the invention, the bearing mechanism consisting of the spring element is unaffected by dirt and the tensioning rail is supported completely without play. Furthermore, a relatively large space is available between the spring elements, which space is available for the electrical or hydraulic adjustment element and its conduit. By supporting each tensioning rail with a plurality of spring elements, a parallel movement of the tensioning rail is achieved during tensioning of the printing plate. The leaf spring supporting the tensioning rail for the front plate end of the printing plate allows elastic movement of the tensioning rail only in the circumferential direction of the printing form cylinder, so that the printing plate is preregistered and fixed in the axial direction. be done.

対応する数の丸棒ばね１２が設けられる。A round bar spring 12 shown in FIG. 1 is attached to a support plate 13 and holds the tensioning rail 4 in its upper part. The support plate 13 is screwed to the bottom of the body groove 3 via screws 14. When actuating the tensioning screw 11, the round bar spring 12 acts like a linkage, so that the tensioning rail 4 moves together with the plate edge 6 approximately parallel to the plate edge 6. . A plurality of round bar springs 12 are provided depending on the length of the tightening rails 4, 5 used. If necessary, the tensioning rail 4 can be segmented in the longitudinal direction;
A corresponding number of round bar springs 12 are provided.

に形成してよい。The means for registering and fixing the printing plate 2 are constructed as tension screws 11 in the illustrated embodiment and rest on the side walls of the barrel groove 3. In order to keep the tensioning screw 11 in constant contact, the support plate 1-13.16 is arranged with some offset relative to the side wall of the barrel groove 3, so that a preload is created. The printing plate 2 is tensioned against this preload. The spring elements (bar spring 12, leaf spring 15) may partially or completely form the force necessary for tensioning the printing plate 2.
